"resolver" is a generic term. I think you are thinking of "named", BIND's

`dig` is a DNS client, not a lwres client, so it'll work as a client for
named. The lightweight resolver is a weird beast that is designed to move
most of the DNS logic out of the libc stub resolver into lwresd. lwresd is
an alias for named which enables the nonstandard lightweight resolver
protocol. BIND doesn't have a command-line lwres client, just some test
lwres is hardly ever used and can mostly be ignored.
